Nomenclature Plectotropis is a substitute name for Thea Albers, 1850, junior homonym of Thea Mulsant, 1846. Martens designated Helix elegantissima L. Pfeiffer, 1849 as type species, which was not originally included in Thea.
General characteristics (Original description in Latin) The shell is openly and deeply umbilicate, lenticular in shape, thin and transparent, and bears a distinct keel. It has 6.5 whorls, the first five increasing slowly in size, and the body whorl does not descend anteriorly. The keel is sharp, compressed, and finely crenulate.
The aperture is axe‑shaped to somewhat rhomboidal. The peristome has a thin, slightly expanded upper margin, while the basal margin is scarcely dilated and is briefly reflected. Albers, J.
